Document Summary
1. 2: atomic structure: orbitals: orbital: describes the volume of space around a nucleus that an electron is most likely to occupy. 1. 3 atomic structure: electron configurations: ground-state electron configuration: the lowest energy arrangement of an atom, which includes a listing of the orbitals occupied by its electrons, 3 rules must be followed to achieve this. This spin can have two orientations, denoted as up and down. 1. 9 sp hybrid orbitals and the structure of acetylene: sp hybrid: the third type of orbital that can be used to form bonds. Typically prevalent when dealing with triple bonds: allow the use of two sp hybrid orbitals rather than two or three p orbitals. The skeleton can consist of chains, branches, and/or rings of bonded atoms: skeletal atoms other than carbon or hydrogen are called heteroatoms . Instead, a carbon atoms is assumed to be at each intersection of two lines (bonds) and at the end of each line.
